Grodan® Gro Block Improved GR6.5 Small 4''

Grodan rock wool hydroponic growing blocks are made to adapt to optimized irrigation strategies for large scale precision production of agricultural crops.

Grodan Improved, developed in partnership with Wageningen University and Research Facility in the Netherlands, is an advanced stone wool substrate that offers precise water distribution, enhanced crop steering and food, ornamental and medicinal herb cultivation solutions for consistent growing and harvest quality.

Features

• Block dimension W x H x L: 10cm x 10cm x 6.5cm / 4'' x 4'' x 2.5''.
• Can be stacked for easy potting up onto the Grodan Gro Slab most appropriate for your culture.
• Designed to fit the facility and crop plan outcomes.
• Advanced wetting technology for superior water distribution, faster rooting, and enhanced plant growth.

• Available in UV exclusion foil with a black inner layer and white outer layer foil to block UV light from the sides of the blocks.
  

Key Benefits

1. Excellent control enabling precision.
   The higher field capacity upon initial saturation, and improved water distribution throughout the height of the block results in improved root growth, enhanced water holding capabilities, and more stable EC behaviour in the root zone. This makes it easier than ever before to control your crop, with even fewer inputs, from propagation through to harvest.
2. Greater steering possibilities.
   The advanced technology used in Grodan Gro Blocks Improved, combined with the uniformity of WC and EC throughout the entire block, provides better vegetative and generative steering. WC and EC can be adjusted more rapidly and efficiently with less leachate required to reduce and stabilize substrate EC. This offers the grower a nimble, flexible substrate that can be steered generatively and vegetatively with a high degree of efficiency.
3. Roots make better use of the entire substrate volume.
   Both the rooting in and rooting through growth phase has improved thanks to the Gro Block Improved technology. Trials have repeatedly shown that the initial rooting in phase in Grodan Gro Block Improved occurs several days faster, speeding up the vegetative phase and time to harvest. The more effective rooting through of the entire substrate volume leads to a visible increase of roots and, thus, better water and nutrient uptake. Naturally, this results in enhanced plant health and productivity from start to finish.

4. Stronger, more vigorous plant development.
   Due to the better developed root system in Grodan Gro Block Improved, the trial results showed increased plant growth, especially during the vegetative phase, in the form of larger plant size, greater stem thickness, and bigger leaves. Ultimately, this can lead to higher yield, while at the same time, the stronger, more vigorous plants show increased resistance to disease.
